Claims (4)
- 기록 매체로부터 재생된 영상 신호를 다른 기록 매체에 녹화(dubbing)하는 영상 신호 녹화 시스템에 있어서, a) 동일 영상 신호가 기록되어 있는 n개의 기록 매체를 통상의 이송 속도의 n배의 속도로 이송하고, 상기 n개의 기록 매체가 서로 1프레임씩 오프 세트한 위치에서부터, 영상 신호를 재생하는 n대(n=2, 4, 6, 8, 16, ....)의 VTR, 상기 VTR의 회전 헤드의 회전 속도는 1배속 재생시의 회전 속도와 동등하고, b) 상기 n대의 VTR에 의해서 재생된 영상 신호에 신호 압축 처리 및/또는 신호 지연 처리를 실시하고, n배속의 재생 신호로서 처리 후의 신호를 출력하는 신호 처리 수단 및, c) 상기 신호 처리 수단으로부터 출력되는 영상 신호를 n배속으로 기록 매체에 기록하는 기록 VTR을 포함하는 영상 신호 녹화 시스템.
- 제1항에 있어서, 상기 n대의 VTR에 기준의 타임 코드 신호를 공급하는 타임 코드 제네레이터, 상기 타임 코드 제네레이터는 서로 1프레임에 상당하는 시간 만큼 값이 상이한 타임 코드 신호를 상기 n대의 VTR에 공급하는 영상 신호 녹화 시스템.
- 제1항에 있어서, 상기 신호 처리 수단은 상기 n대의 VTR로부터 공급되는 영상 신호의 시간 축을 각각 1/n로 압축하는 n개의 시간축 압축 수단과, 각각 상기 n개의 시간축 압축 수단의 출력 신호가 공급되며, 공급된 신호를 각각 소정 시간만큼 지연하는 n-1개의 지연 수단과, 상기 n개의 지연 수단의 출력 신호 및 상기 시간축 압축 수단의 출력 신호를 선택적으로 출력하는 신호 선택 수단 및, 상기 신호 처리 수단의 출력 신호가 공급되며, 공급된 신호를 아나로그 신호로 변환하는 D/A변환 수단을 갖는 영상 신호 녹화 시스템.
- 제3항에 있어서, 상기 기록 VTR이 아나로그 VTR인 영상 신호 녹화 시스템.
